APPARATUS FOR COMBINING HOT AIR AND STEAM FOR HEATING PURPOSES AND POWER.

SPECIFICATICN forming part of Letters Patent No. 320,768, dated June 23, 1885.

Application filed March 26, 188 1.

To all whom it may concern:

Be it known that we, \VILLIAM T. FENION,

of the city and State of New York, and DAVID S. B. BENNET, of Brooklyn, in the State of New York, have jointly invented an Improvement in Apparatusfor Combining Steam and Hot Air for Heating and Other Purposes, of which the following is a specification.

' This invention relates to the pumping or forcing of atmospheric air into steam, and heating the atmosphere and the steam, and conveying the heated mixture to radiators or other heating apparatus, or to engines at a distance.

By this improvement the atmosphere com pels a circulation of the steam, and the heat is conveyed a great distance through pipes with but little loss.

In the drawing our improvement is illustrated by a perspective view, partially sectional, to show the fire-chambers.

In carrying our invention into practice we supply steam from any suitable source for instance, through the pipe Eand into such pipe atmospheric air is forced, preferably through an injector-nozzle, so that the rush of atmosphere draws the steam into contact and mixture with it, and back-pressure is avoided. Thence the air and steam commingled pass through the coil D, preferably in the chamber D, containing the products of combustion from the fire B, so as to absorb as much heat as possible from the gases and prevent loss of heat passing to the chimney. The steam and atmosphere become sufficiently heated, and are conveyed by pipes to any desired distance, and used for purposes of power in engines or for heating purposes.

We have shown and prefer to use the steam from the high-pressure boiler A to work the steamcylinders G of the air-pump C, which forces the atmosphere into the pipe F, and from that into the pipe E,which conveys away the exhaust-steam from the steam-cylinders C of the air-pump O.

The steam from the boiler B is admitted (No model.)

into the main pipe G, to pass with the heated air and steam to the Working apparatus. Check-valves may be applied at H and H to prevent the steam and air passing in the wrong direction.

It is to be understood that we not claim pumping air into steam, nor the superheating of steam, as these have beenemployed.

In our improvement, as before described, the heat is added to the air after the exhauststeam is mixed with it, but if the exhauststeam is not passed into the air-pipe, the air will be heated and brought into contact with the steam issuing from the boiler B into the pipe G.

In all instances the heat acts to elevate the temperature of the steam and increase its volume and lessen condensation. At the same time the heated atmosphere under pressure" compels the rapid circulation of the steam to the working or heating apparatus at a distance, so that the efficiency of the steam for power or heat is greatly augmented.

In all instances the heated air serves to dry the steam and to increase the volume of heat conveyed with the steam. At the same time the atmosphere under pressure compels the hind the bridge-wall, through which coil the air is passed, and a connection for the exhauststeam from the steam air-pump to the pipe through which the air is forced, substantially as set forth.
